API 5L Gr .B Pipes

Method of calculating the pressure of API 5L Gr .B Pipes
To know wall thickness and diameter of API 5L Gr .B Pipes(different materials has different tensile strength)
Pressure = (wall thickness * 2 * tensile strength of the seamless pipe)/(OD * coefficient)
: To know diameter and pressure of seamless pipe to withstand wall thickness calculation methods:
Wall thickness = (pressure * diameter * coefficient)/(2 * tensile strength of pipe material)
The representation of API 5L Gr .B Pipes pressure coefficient:
The Pressure P<7MPa coefficient S = 8
7 <pipe pressure P <17.5 coefficient S = 6
The pressure P> 17.5 Coefficient S = 4
